Abstract
In one embodiment, a method includes receiving information on layer 2 topologies at a network device in a core network, mapping one or more Virtual Local Area Networks (VLANs) to the layer 2 topologies to provide differentiated services in said layer 2 topologies, defining multiple paths for each of the layer 2 topologies, and forwarding a packet received at the network device on one of the multiple paths. An apparatus for providing differentiated services in layer 2 topologies is also disclosed.
Claims20
A method comprising:
- receiving information on layer 2 topologies at a network device in a core network;
- mapping one or more Virtual Local Area Networks (VLANs) to said layer 2 topologies to provide differentiated services in said layer 2 topologies;
- defining multiple paths for each of said layer 2 topologies;
- and
- forwarding a packet received at the network device on one of said multiple paths.
An apparatus comprising:
- a database for storing information on layer 2 topologies;
- a database for storing mappings between said layer 2 topologies and one or more Virtual Local Area Networks (VLANs) to provide differentiated services in said layer 2 topologies;
- and
- a processor configured to compute multiple paths for each of said layer 2 topologies and forward packets on said multiple paths.
An apparatus comprising:
- means for receiving information on layer 2 topologies at a network device in a core network;
- means for mapping one or more Virtual Local Area Networks (VLANs) to said layer 2 topologies to provide differentiated services in said layer 2 topologies;
- means for defining multiple paths for each of said layer 2 topologies;
- and
- means for forwarding a packet received at the network device on one of said multiple paths.
